SIDE DELIVERY BAKE Original Filed Nov. 2.8, 1955 IN VEN TOR.

United States Patent Oice Patented Oct. 29, 1963 rlhis inventionIrelates to a raking apparatus which can be attached to the power lifitof a tractor provided with a number of freely rotatably raking members.In distinction to earlier proposed raking attachments, the rakingmembers are not mounted on the frame so as to move up and downindependently, but rather provide support for 4the frame during theraking action.

More specifically, the invention is directed to a raking attachment incombination with a tractor having a power lift mechanism including apair of transversely spaced vertically swingable l-inks, comprising aframe having mounted thereon a plurality of freely rotatable rakingmembers in echelon disposed obliquely to the direction of travel,connecting means provided at transversely spaced points on said framefor pivotally attaching the frame to said links to -allow free movementof the frame in a vertical plane and serving to prevent movement of saidframe in a lateral direction relative to the direction of movement ofthe tractor, said raking attachment including at least some of saidraking members constituting supporting members for the frame.

Fllhis is a division of our application Serial No. 549,482, led Nov. 28,1955, to issue las Patent No. 2,933,878, on April 26, 1960. s

The invention will be more readily understood by reference to theaccompanying drawings and the following description in which a specificembodiment of the inveniton is set forth by way of illustration ratherthan by way of limitation.

-FlGURE 1 shows a plan view of an implement attached to a tractor,

FIGURE 2 shows a side elevation of the implement when viewed in thedirection of the arrow II in FIG- URE 1,

FIGURE 3 shows a plan view of the implement in a working position inwhich it serves as a tedder,

FIGURE 4 shows a side elevation of a modification for mounting rakewheels on the implement'shown in FIGURE l,

FIGURE 5 shows the implement shown in F1GURES 1-4 in a position fortransportation.

Referring to FIGURES 1 to 3, a tractor 100 carries a three-point liftingdevice 100A having three link ends 101, 102 and 103. Pins 104, formingpart of the connecting means for connecting the frame of the implementto the tractor, are pivoted in'- the link ends 101 and 102, the pinsconstituting the extremities of an axle 105. Two supporting 'ba-rs 106and 107 extending obliquely upwards are hinged to the axle 105 at hinges106A and 107A, the upper ends `of the supporting bars 106 and 107 beinghinged to the link end 103.

A horizontal bow 108 is attached to axle 105. Bow 108 includes a portionwith holes 109 which co-operate with la locking pin 110. In order toadjust the effective working width of the implement, end 111 of sleeve112 is slideable along the aforesaid portion of bow 108 and has afurther hole for pin 110 which can be secured in various positionsdepending upon which one'of the holes 109 registers with the hole in theend 111 to provide an entry for the pin 110. Thus pin 110 secures bow108 and sleeve 112 against relative angular movement. The other end 113of sleeve 112 is hingedly connected about a vertical axis to axle 105.

A spring 128 connects the link end 103 by means of a hook 115 to bow108. By means of this spring 128 the Ilifting device 100A at leastpartially supports the weight of the frame since the latter is hingedlyconnected to the lifting of the tractor about a horizontal axis throughpins 104 lying transverse to the direction of travel. A chain 114 (seeyFIGURE 2) also connects line end 103, by means of Lhook 115, to bow108.

Shaft or second frame beam 116 is rotatably supported in sleeve 112, andcan be secu-red against rotation in any one of several positions thereinby means of a pin 117 which can be entered in a hole in the sleeve 112and in a desired hole of several holes in the shaft.

An end of shaft or second frame beam 116 which cornprises an elongatedframe beam is connected to the center of tube or first frame beam 118 ofthe frame of the inrplement, the connection being reinforced by means ofstruts 119 and 120. Four arms 125, 125A, 125B and C parallel to theshaft 116 are immovably attached to tube 118 at 121, 122, 123 and 124.Rake wheels 126, 126A, 126B and 126C are freely rotatable on arms 125,125A, 125B and 125C, respectively. Each of said rake wheels consists ofa ihub 33 (see FIGURE 2), a rim 34 and steel wires 35, each of thelatter being attached at `one end to the hub 33 and passing throughapertures in the rim 34. On the inner side of rim 34, steel wires 35 arelocated in the plane of .rim 34 and are non-radial. .lust outside rim34, each steel wire is bent at 36 to form a tine 38 and a support 37 forthe tine. Each tine is substantially parallel to that part of steel wire35 which is located at the inner side of rim 34.

Rake wheels 126, 126A, 126B and 126C constitute ground engaging membersso that the frame in operative position maintains itself :atsubstantially the same distance above the ground.

In the construction of the implement which is shown in FIGURES l and 2,the frame can easily be inverted. It is only necessary to lift the framea sufficient height Ifrom the ground 129 by means of the lifting deviceof the tractor, and subsequently to turn the shaft 116, in the sleeve112, through and when itis then lowered, it will stand on the ground 129in the position shown in FIGURE 3.

In the working positions shown in FIGURES l and 3, the implement is,respectively, a side delivery rake and a tedder.

It is preferable not to secure shaft 116, in sleeve 112 in the workingpositions, but rather to allow the shaft to 'turn through a small angleso as to take account of the unevenness of the ground thereby permittingthe weight of the frame to be taken on rake wheels 126, 126A, 126B and126C and the lifting device.

With reference to FIGURE 4, it has been found advanrtageous to have tube118, when the implement serves as -a side -delivery rake (as shown 4inFIGURE 1), at a higher location than the arms of the rake wheels, i.e.in the position 118A. As a result, arm supports 125D are arranged toextend obliquely upwards from rake wheel 126D and high windrows willseldom `Contact the tube 118A. In the working position in which theimplement serves as a tedder, the tube 118A is then situated lower thanthe arms of the rake wheels, but, of course, the material will not beheaped up to such an extent during tedding as occurs in side deliveryraking.

'Ilhe implement shown in FIGURES 1 to 4 can be lifted to the positionshown in FIGURE 5 in order to facilitate transportation thereof-it beingobvious that in this position the implement occupies less transversespace than in its working positions. If the lifting device of the 3tractor is suitably arranged, the transportation position can easily heattained by lifting the shaft 116 and then securing it in the requiredposition in the sleeve 112.

After completion of the transportation, the implement can be loweredinto either the position in which it can serve as a side delivery rakeor the position in which it can serve as a tedder depending upon thedirection of rotation of the implement prior to lowering.

The `above description and drawings disclose a single embodiment of theinvention, and specific language has been employed in describing `theseveral gures. It will, nevertheless, be understood that no limitationsof the scope of the invention are thereby contemplated, and that variousalterations and modications may be made such as would occur to oneskilled in the art to which the invention relates.
